摘要：
Protein aggregation has been observed in-situ in lysozyme solutions under an internal electric field using a forward light scattering technique. Light scattering at small forward angles revealed that the application of a low voltage to the protein solutions significantly promotes aggregate formation. The solutions required a specific amount of time exposed to an electric field before the solution had undergone sufficient protein aggregation. The in-situ results from forward light scattering allow the characterization of the process. (C) 2011 American Institute of Physics. [doi:10.1063/1.3648114]
